This is just a quick addendum to the post I made yesterday on the subject of the aerobic base ride. In that post I commented that your heart rate should stay primarily in zone 2. This allows you to complete a long, steady endurance workout that boosts aerobic fitness. One of the athletes I coach did such a ride yesterday. Here you can see a chart which shows how his heart rate was distributed by zones. This is an excellent example of what the heart rate distribution should look like after such a workout.
